Referring to fig. 1 and 2, in some embodiments, the bucket-shaped structure is formed by a plurality of support sections 140 and fire cloth 130, that is, after the bucket-shaped structure is divided into a plurality of bucket wall sections, each bucket wall section contains at least one support section 140. In view of the above, the barrel-shaped structure includes three barrel wall sections, and since the outer peripheral dimension of the first barrel wall section 150 is approximately the same in the axial direction thereof, the dimension of the support portion 140 located in the first barrel wall section 150 is also approximately the same, and similarly, the dimension of the support portion 140 located in the second barrel wall section 160 is approximately the same as the outer peripheral dimension of the second barrel wall section 160, and the dimension of the support portion 140 located in the third barrel wall section 170 is approximately the same as the outer peripheral dimension of the third barrel wall section 170.

In some embodiments, the structure of the supporting portion 140 may be one of a circular ring shape, an elliptical ring shape, or a polygonal ring shape. The cross-sectional shapes of the main body 100 surrounded by the supporting part 140 and the fire extinguishing cloth 130 of different ring structures are different, and the shapes of the first port 110 and the second port 120 are changed according to the shape of the supporting part 140.

As can be seen from the geometric principle, in the planar patterns of various shapes, the area of the circle is the largest when the circumference is the same, and therefore, the area of the circular second port 120 is larger than the area of the second port 120 of other shapes. That is, the inside of the main body 100 surrounded by the support part 140 and the fire-extinguishing cloth 130 in the circular ring structure has the largest accommodation space compared to the other support parts 140 in the circular ring structure, so that the fire-extinguishing cover has a larger fire-extinguishing range.

In some embodiments, since the outer diameter of the first barrel section 150 is larger than the outer diameters of the second barrel section 160 and the third barrel section 170, the outer diameter of the supporting portion 140 disposed on the first barrel section 150 is also larger than the outer diameters of the supporting portions 140 of the other barrel sections, so that the first port 110 at the bottom of the first barrel section 150 also has a larger caliber, and thus the fire extinguishing cover can cover a larger range of target fire sources, and the fire extinguishing range of the fire extinguishing cover is improved.

In some embodiments, the fire extinguishing cloth 130 and each of the supporting parts 140 may be coupled by a sewing line, that is, a portion of each of the supporting parts 140 contacting the fire extinguishing cloth 130 is coupled by a sewing line to form the main body 100. Further, the supporting part 140 of each loop structure may be sewn inside the fire-extinguishing cloth 130. In addition, the ring-shaped structural support 140 may directly support the fire-extinguishing cloth 130 and form the main body 100, i.e., the ring-shaped structural support 140 having a certain elasticity is directly fixed inside the fire-extinguishing cloth 130 by the elasticity of the support 140 and supports the fire-extinguishing cloth 130 to form the main body 100.

In some embodiments, the fire extinguishing cloth 130 at the first port 110 may wrap the supporting portion 140 at the first port 110 to improve the wear resistance and high temperature resistance of the supporting portion 140 at the first port 110, thereby improving the service life of the fire extinguishing cover. The fire extinguishing cloth 130 at the second port 120 can wrap the supporting portion 140 at the second port 120, thereby improving the wear resistance and high temperature resistance of the supporting portion 140 at the second port 120 and further improving the service life of the fire extinguishing cover.

In some embodiments, the thread connecting the fire-extinguishing cloth 130 and the supporting portion 140 may be made of fireproof material, so as to prevent the thread from being burned out due to high temperature during the fire-extinguishing process of the fire-extinguishing cover, thereby easily separating the supporting portion 140 from the fire-extinguishing cloth 130, and further damaging the fire-extinguishing cover. The material of the suture thread can be graphitized carbon fiber or ceramic fiber with fire-proof performance. The material of the stitches may also be the same as the fire extinguishing cloth 130. The high-temperature resistance of the fire extinguishing cover is improved by adopting the suture prepared from the fireproof material, so that the service life of the fire extinguishing cover is prolonged.

In an embodiment of the present invention, the material of the supporting portion 140 includes at least one of flame retardant glass fiber, flame retardant thermoplastic material and high temperature resistant metal. Particularly, supporting part 140 is as one of the important component parts of the fire extinguishing cover of the embodiment of the utility model, equally need to have anti fire-retardant and high temperature resistance performance, prevents in the use of fire extinguishing cover that supporting part 140 takes place to warp or burn out because of high temperature to lead to the fire extinguishing cover damage. In addition, the supporting part 140 may have an elastic property, which can prevent the fire extinguishing cover from being damaged due to the easy breakage of the supporting part 140 caused by external force during transportation or use due to its too high hardness. Therefore, the support part 140 is made of the elastic flame-retardant glass fiber, the flame-retardant thermoplastic material or the high-temperature-resistant metal material, so that the service life of the fire extinguishing cover can be remarkably prolonged.

Referring to fig. 1 and 2, in some embodiments, the fire extinguishing cloth 130 connected between the respective supporting parts 140 can be folded in an axial direction of the main body 100. In the present embodiment, the fire extinguishing cloth 130 between the respective supporting parts 140 has certain plasticity, so that the fire extinguishing cloth 130 between the respective supporting parts 140 can be folded and unfolded in the axial direction of the main body 100, thereby enabling the fire extinguishing cover to be folded and unfolded in the axial direction of the main body 100. In some embodiments, the fire extinguishing cover can be reduced in volume by folding the fire extinguishing cloth 130 between the respective supporting parts 140 when it is not necessary to unfold the fire extinguishing cover. Therefore, the fire extinguishing cover is designed into a foldable and unfolded structure, so that the space occupied by the fire extinguishing cover when the fire extinguishing cover is not required to be unfolded for use is reduced, and the portability of the fire extinguishing cover in the carrying process is improved.

The inside of the first barrel wall section 150 of the fire extinguishing cover of the embodiment of the utility model requires a large accommodation space, so the supporting parts 140 arranged at a plurality of intervals are required to be used as the supporting structure of the first barrel wall section 150, and the outer diameter of each supporting part 140 is the same.
